A pumpkin is launched from the top of a 20-foot tall platform at an initial velocity of 84 feet per second. The height, h(t), of the pumpkin at time t seconds after launch can be modeled by the equation h(t)=−16t2 +84t+20.
a. Find the maximum height reached by the pumpkin.
b. How long did it take for the pumpkin to reach the maximum height?
c. When does the pumpkin reach a height of 100 feet?

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
